Under this subscription model, the client or customer is the entity that owns or has direct oversight of the organization or system being managed whereas the Managed Services Provider (MSP) is the service provider delivering the managed services. The client and the MSP are bound by a contractual, service-level agreement that states the performance and quality metrics of their relationship.
Managed IT services heralded a proactive approach to IT, attempting to conduct maintenance, upgrades, system monitoring and issue resolution on a routine basis, with the goal of preventing problems before they started. Automation, increased Internet capabilities and cloud computing allowed for monitoring and issue resolution to be provided remotely, enabling more efficient processes and a consolidation of resources.
Cloud computing has allowed managed IT services to expand beyond the regions and borders that would constrain the average break/fix IT through the adoption of Software as a Service (SaaS) technologies, as well as Infrastructure as a Service (IaaS) and Platform as a Service(PaaS) also. These capabilities allow managed IT services to scale at a rate dramatically larger and faster than in-house IT operation or break/fix providers.
